In the alps, a comfortable hike can turn quickly into a life-threatening situation. Do not think that there is somebody there to rescue (if even find) you. Read online hike descriptions before going on a hike, and make sure to understand in which context they are written. When you go to a completely new area, take an easy approach rather than a challenging one.
Modern clothes and equipment, weather forecasting, mobile networks and GPS and digital maps make hiking a very comfortable experience nowadays. But one has to use it correctly and be aware of where it cannot help.
